The Dynamics Of tHe Local Group
The Dynamics Of tHe Local Group
Work led by Dr. Ekta Patel, Dr. Nico Garavito Camargo, and Dr Katie Chamberlain
Modeling the motions of galaxies in our Local Group (the Milky Way, Andromeda and the galaxies that orbit them) and placing them in a cosmological context.

The LMC and SMC
The LMC and SMC
Hydrodynamic and N-body simulations and observational studies of the evolution of the LMC and SMC, the largest satellites galaxies of the Milky Way. (Data from Besla+2013,2012 simulations is available upon request)
Ongoing work led by Himansh Rathore, Hayden Foote, Dr Paul Zivick, and Dr Yumi Choi

Interactions Between Dwarf GAlaxies
Interactions Between Dwarf GAlaxies
Work led by Dr. Katie Chamberlain, Dr. Sarah Pearson & the Tiny Titans Collaboration.
Dynamical modeling, cosmological statistics, and observational studies of dwarf galaxy pairs across cosmic time.

Understanding Dark Matter
Understanding Dark Matter
Ongoing work led by Hayden Foote
Simulations to test the nature of dark matter and make predictions for direct detection experiments and observational surveys of the stellar halo. A highlight is a new prediction for the impact of a dark matter-dominated Ultra Faint Dwarf Galaxy and the Cetus-Palca Stream (Foote+2024).

CircumGalactic Medium of the Milky Way
CircumGalactic Medium of the Milky Way
Ongoing work by Dr David Setton and Chris Carr
Understanding the circumgalactic medium through hydrodynamic simulations of the LMC and its 30 kpc bow shock.
The Milky Way - Andromeda Collision
The Milky Way - Andromeda Collision
Simulations of the future fate of our Milky Way and its nearest Galactic neighbor, the Andromeda Galaxy.
These simulations are being utilized as the basis for semester long research projects in ASTR400B : Galaxies and Cosmology, a class for astronomy seniors at UArizona.
